Coupon Types Reference

IMPORTANT — Type Translation Rule: When displaying the coupon type, map coupon_type strictly to the Display Name. You may translate Display Names to match the response language, but the mapping must be exact — never swap or conflate two different types. Critical distinction: position_voucher (Position Trial Voucher) is a position-based trial voucher — translate as "仓位体验券" in Chinese, never as "合约体验金"; contract_bonus (Futures Bonus) is futures trial funds — translate as "合约体验金". They are completely different products.

Classify the user intent and route to the matching reference document:

Intent	Example Phrases	Route to
List available coupons	"What coupons do I have?", "Show my available coupons", "Do I have any vouchers?", "Check my coupon balance"	Read INLINECODE74
Search by coupon type

"Do I have a commission rebate voucher?", "Check if I have a futures bonus", "Show my VIP trial cards" | Read references/list-coupons.md | | View coupon details | "Show details of my commission rebate coupon", "What are the details of this voucher?", "How much is left on my coupon?" | Read references/coupon-detail.md | | View usage rules | "What are the rules for this coupon?", "How do I use this voucher?", "What are the terms of my futures bonus?" | Read references/coupon-detail.md | | Trace coupon source | "How did I get this coupon?", "Where did this voucher come from?", "What activity gave me this coupon?" | Read references/coupon-detail.md | | Query expired/used coupons | "Show my used coupons", "List my expired vouchers", "What coupons have I used?" | Read references/list-coupons.md | | Unclear | "Tell me about my coupons", "coupon help" | Clarify: ask if user wants to list all coupons or check a specific one |

Execution

1. 1. Identify user intent from the Routing Rules table above.
2. Load the corresponding reference document.
3. Follow the workflow in that document step by step.
4. All operations are read-only — no confirmation gate required.

Error Handling

Situation	Action
Coupon not found	Coupon record does not exist or does not belong to current user. Ask user to re-check which coupon they meant; re-fetch list to get valid IDs.
Invalid coupon type

coupon_type is not a recognized enum value. Map user's natural language to the Coupon Types Reference table and retry. | | No coupons returned | Inform user no coupons match the query. Suggest earning coupons through tasks, activities, or referrals. | | Coupon type unrecognized by user | User mentions a vague or informal name. Clarify by listing the closest matching type names from the Coupon Types Reference. |

Safety Rules

• - All operations in this skill are read-only (query only, no writes).
• Never request or expose user API secrets in the conversation.
• Do not infer or guess coupon IDs — always obtain them from the list API first.
